To enable efficient use of phosphorylation information in various proteomes, we have created a database called PHOSIDA for PHOsphorylation SIte DAtabase.
PHODISA stores phosphorylation data mainly from our own proteomics study. Proteins of interest can be searched via accession numbers of various databases (e.g., IPI database, Swissprot), gene names, symbols or sequences. In addition to phosphorylation sites, general information based on Swissprot, such as molecular weight, sequence, functions, references, motifs, domains, active sites and further features, is also provided. We include sequence alignments of the entries of various databases to normalize amino acid positions.
For each phosphorylation site, information such as kinase motif, localization p-value and flanking sequence is shown. Furthermore, phospho-peptides are presented along with their Mascot scores, PTM scores, the available dynamic profiles in cell signaling study, cluster information, etc.
PHOSIDA helps to assign peptides to proteins. Entries sharing the same phospho-peptides are listed, each indicated with the number of its overall detected peptides.
